Application January 14,

s claims.

The object of my invention vis to provide an illuminable water spraying device, preferably in the lform of a portable revolving lawn sprinkler.

In the warm evenings of the summer, lawn sprinkling is frequently done at night. The purpose of my invention is to utilize such spraying 'as a means for simultaneously producing a fountainlike spray, illuminated in changing colors; thus adding a charm to sitting out-of-doors in the summer evening.

A further lobject of my invention is to incorporate my invention in a portable revolving lawn sprinkler in such a way that the latter may be ordinarily used just as a merelawn sprinkler.

A further object of my invention is to provide a device in which the operating parts are ary ranged and housed with regard to the sthetic eect; also a device which may be made at reasonable cost; in other words, adding comparatively little to the cost of the ordinary revolving lawn sprinkler.

I attain my objects in an illuininable sprinkler comprising a tubular standard .adapted to be connected with a water service pipe, the sprinkler being of the revolving type, a horizontal varicolored light screen carried by the sprinkler and means for projecting the rays of an illuminating element thru said vari-colored screen, thus producing constantly changing light effects and pref,-

. erably I provide a sprayer above the sprinkler for projecting upwardly sprays to be illuminated by the light rays.

The further details of my invention and of its construction and use are hereinafter described `with reference to the accompanying drawing.

In the drawing:

Fig. l shows an elevation of a portable lawn sprinkler embodying my invention in its most complete form; f

Fig. 2 shows a vertical central section of the operating parts of the lawn sprinkler shown in Fig. 1;

Fig. 3 shows a plan or top view of the sprinkler;

Fig. 4 shows a section approximately on the line 4 4 of Fig. 2, the parts shown in full; and

Fig. 5 shows a detail of the skeleton wall frame and housing which may be employed in the construction of my invention.

a is a portable standard on which is mounted a tubular standard b provided with a hose or pipe coupling c for connecting a hose as d with the standard b. The standard b is provided with a lower lateral branch e controlled by a valve and an upper branchy controlled by a valve h.

On the branch e is rotatably mounted a re- 1932. seria1N0.5s6,5s2

volving sprinkler head i having radial arms i terminating in nozzles y'. The sprinkler head z' carriesa pedestal 7c on which to mount the figure as Z. The upper branch y has a sprinkler ring m adapted to project a spray of water upward as indicated at 11.` in Fig. 1. The sprinkler head iY carries a vari-colored light screen o which may consist of segments of colored celluloid as indicated by o in Fig. 3. The hollow standard b is provided with a bracket p which carries a housing q in which is mounted an electric lamp bulb r. This bulb is of the kind employed in automobile headlights and is connected by wires s with an electricity circuit, a transformer being included in the circuit sto permit the use or the desired small lamp bulb. Y

The housing q is provided with a parabolic reflector element t, and the housing q above the lamp bulb r is covered by a water'shedding shield u` so as to protect theY interior of the housing l1 from the water dripping from the sprinkler i and spray ring m. On the housing q is mounted a housing wall c lwhich may consist of a skeleton wall frame w shown in Fig. 5 and sections of translucent colored celluloid x, xv. The revolving sprinkler is in'closed-by a housing wall y supported on the screen o, thru which'the nozzles 1' extend, as shown in Fig. 4.

`lin the operation of my illuminable sprinkler, if the same is to be'used for lawn sprinkling purposes merely, the valve f alone is opened and the valve h is kept shut. When so arranged, my sprinkler will operate just as an ordinary lawn sprinkler of the revolving sprinkler type. While so operated, by turning on'the electricity ourrent of the lamp: bulb r, rays of colored light will project upwardly thru the light screen o. This effect, however, is rendered much more beautiful and efiectiveby partially closing the valve f and opening the valve h, in so doing, projecting a spray of water upwardly rom the spray ring m; this spray changing in color with the rotation of the sprinkler i dueto the travel of the color sections of the f light screen o carried by the sprinkler i.

' In the drawing the arrows indicate the projection of the water from the heads of the revolving sprinkler i and the spray ring m.

The vari-colored lighty screen o is preferably provided with an annular wall a constructed inv the main of 'translucent colored material, in thatV way adding to the coloring effect of 'my lawn sprinkler when operating while illuminated.

I claim: I
